After yesterday's legal arguments, the hearing resumed with evidence from the prosecution lawyer Gerrie Nel and investigating officer Hilton Botha, followed by cross-examination of Botha by Barry Roux of the defence.

Nel claimed that a female witness heard an argument between Steenkamp and Pistorius between 2am and 3am, and that the model was dressed when she was fatally shot.

He added that Pistorius's actions and his phone calls that night indicated planning and that there was premeditated and "deliberate aiming of shots at the toilet from about 1.5 metres".

Botha, who arrived at Pistorius's house at 4.15am, said that Steenkamp was found dead at the foot of the staircase of the ground floor wearing white shorts and a black vest, covered in towels.

However, under later cross-examination, Botha admitted that the female witness did not specifically identify Steenkamp or Pistorius as the voices she heard, and that she was situated 600 metres from the Pretoria home.

Botha opposed bail for the athlete, suggesting that he could be a flight risk given the serious nature of the alleged crime and the possible 15 years to life sentence.

He noted that details were found of offshore accounts held by Pistorius and a house owned in Italy not mentioned during yesterday's testimony.

Botha said that charges of possession of unlicensed ammunition would be added to the case, after unlicensed .38 Special rounds were found in a bedroom safe.

He said that gunshot wounds - some through Steenkamp's clothes - were positioned on the right side of her head above her ear, her right arm and hip.

The officer mentioned the accidental firing of a gun at a restaurant, which involved Justin Divaris who gave testimony in Pistorius's defence yesterday, and mentioned another incident where the athlete allegedly threatened a man in an argument about a woman.

The witness to the couple's alleged fight in the early hours of the morning claimed to have heard gunshots, seen the lights on, heard a woman scream and then heard more gunshots.

Under cross-examination by defence lawyer Roux, Botha conceded that Pistorius had told him at the scene that he first thought he was shooting at a burglar.

Roux contested the version of events painted by Botha, arguing that the shots were fired from the bathroom door and that it was dark inside the bedroom with the curtains drawn.

With regards to the witness, Botha conceded that the woman who said that the lights were on also miscounted the number of shots. He countered that the witness heard several shots, a 17 minute gap, and then several shots more - with the number of shots fired being uncertain.

When Roux noted that the witness was positioned 600 metres from Pistorius's home, gasps were heard in the courtroom.

Roux went on to say that postmortem results found that Steenkamp's bladder was empty, not as a result of leaking or perforation - suggesting that she had gone to the toilet at around 3am.

He claimed that Steenkamp may have locked herself in the toilet after hearing Pistorius yell about an intruder.

Botha conceded under further questioning that Steenkamp's body did not show signs of either an assault or defensive wounds. He accepted that there was no evidence at the crime scene which was directly inconsistent with Pistorius's own version of events.

The hearing adjourned for lunch and will resume at 1.30pm local time (11.30am in the UK).

As the case has been designated a schedule six, rather than schedule five matter, it is unlikely that Pistorius will be granted bail unless the defence prevent compelling evidence why he should.
